Timed-Release Encryption With Master Time Bound Key (Full Version)
timed-release encryption Weil pairing bilinear Diffie-Hellman problem
2019/8/8
Timed-release encryption allows senders to send a message to a receiver which cannot decrypt until a server releases a time bound key at the release time. The release time usually supposed to be known...
Timed-release encryption is a kind of encryption scheme that a recipient can decrypt only after a specified amount of time T (assuming that we have a moderately precise estimate of his computing power...
A Conditional Proxy Broadcast Re-Encryption Scheme Supporting Timed-Release
timed-release encryption unidirectional conditional proxy broadcast re-encryption bilinear map.

To allow a delegator not only to delegate the keyword-controlled decryption rights of a broadcast encryption to a set of speci ed recipi- ents, but also to control when the decryption rights will be d...
General Certificateless Encryption and Timed-Release Encryption
security-mediated certificateless encryption timed-release encryption standard model
2009/6/2
While recent timed-release encryption (TRE) schemes are
implicitly supported by a certificateless encryption (CLE) mechanism,
the security models of CLE and TRE di er and there is no generic
transf...
Let n be a large composite number. Without factoring n, the validation of a
2t (mod n) given a, t with gcd(a; n) = 1 and t < n can be done in t squarings modulo n. For
t n (e.g., n > 21024 and t <...
Timed-Release and Key-Insulated Public Key Encryption
timed-release authenticated encryption key-insulated encryption
2009/3/27
In this paper we consider two security notions related to
Identity Based Encryption: Key-insulated public key encryption, introduced
by Dodis, Katz, Xu and Yung; and Timed-Release Public Key
crypto...
Scalable, Server-Passive, User-Anonymous Timed Release Public Key Encryption from Bilinear Pairing
timed release encryption bilinear pairing anonymity
2009/3/27
We consider the problem of sending messages into the future, commonly known as timed
release cryptography. Existing schemes for this task either solve the relative time problem
with uncontrollable, ...
Revisiting the Security Model for Timed-Release Encryption with Pre-Open Capability
Security Model Timed-Release Encryption Pre-Open Capability
2008/12/17
The concept of timed-released encryption with pre-open ca-
pability (TRE-PC) was introduced by Hwang, Yum and Lee. In a TRE-
PC scheme, a message is encrypted in such a way that it can only be
decr...
